is risk of fire or electric shock.
•For installation, removal or reinstall , always contact the dealer or an Authorized Service Center. There is risk of fire, electric shock, explosion, or injury.
•Do not install the product on a defective installation stand. Be sure that the installation area does not deteriorate with age. It may cause product to fall.
• Never install the outdoor unit on a moving base or a place from where it can fall down.
The falling outdoor unit can cause damage or injury or even death of a person.
•In outdoor unit the step-up capacitor supplies high voltage electricity to the electrical components. Be sure to discharge the capacitor completely before conducting the repair work.
An charged capacitor can cause electrical shock.
•When installing the unit, use the installation kit provided with the product. Otherwise the unit may fall and cause severe injury.
•Indoor/outdoor wiring connections must be secured tightly and the cable should be routed properly so that there is no force pulling the cable from the connection terminals. Improper or loose connections can cause heat generation or fire.
•Safely dispose off the packing materials. Like screws, nails, batteries, broken things etc after installation or svc and then tear away and throw away the plastic packaging bags. Children may play with them and cause injury.
•Be sure to check the refrigerant to be used. Please read the label on the product. Incorrect refrigerant used can prevent the normal operation of the unit.
Operation
•When the product is soaked (flooded or submerged) in water , contact an Authorized Service Center for repair before using it again. There is risk of fire or eletric shock.
•Be sure to use only those parts which are listed in the svc parts list. Never attempt to modify the equipment. The use of inappropriate parts can cause an electrical shock, excessive heat generation or fire.
•Do not touch , operate, or repair the product with wet hands. Hold the plug by hand when taking out. There is risk of electric shock or fire.
•Do not place a heater or other heating appliances near the power cable. There is risk of fire and electric shock.

| <![if ! IE]> <![endif]>ENGLISH |
|
• Do not allow water to run into electric parts. Install the unit away from water sources. There is risk of fire, failure of the product, or electric shock.
• Do not store or use or even allow flammable gas or combustibles near the product. There is risk of fire.
• Do not use the product in a tightly closed space for a long time. Perform ventilation regularly. Oxygen deficiency could occur and hence harm your health.
• Do not open the front grille of the product during operation. (Do not touch the electrostatic filter, if the unit is so equipped.) There is risk of physical injury, electric shock, or product failure.
• If strange sound, smell or smoke comes from product.Immediately turn the breaker off or disconnect the power supply cable. There is risk of electric shock or fire.
• Ventilate the product room from time to time when operating it together with a stove, or heating element etc. Oxygen deficiency can occur and hence harm your health.
• When the product is not to be used for a long time, disconnect the power supply plug or turn off the breaker. There is risk of product damage or failure, or unintended operation.
• Take care to ensure that nobody especially kids could step on or fall onto the outdoor unit. This could result in personal injury and product damage.
• Take care to ensure that power cable could not be pulled out or damaged during operation. There is risk of fire or electric shock.
• Do not place ANYTHING on the power cable. There is risk of fire or electric shock.
• When flammable gas leaks, turn off the gas and open a window for ventilation befor turning on the product. Do not use the telephone or turn switches on or off. There is risk of explosion or fire.
! CAUTION
Installation
•Two or more people must lift and transport the product. Avoid personal injury.
•Do not install the product where it will be exposed to sea wind (salt spray) directly. It may cause corrosion on the product.
•Install the drain hose to ensure that the condensed water is drained away properly. A bad connection may cause water leakage.

• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant levels may cause failure of product.
• Please install safely at a place that can sufficiently endure the weight of the product.
If the strength is not sufficient, the product may fall and cause injury.
Operation
•Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of property.
•Do not block the inlet or outlet of air flow. It may cause product failure.
•Use a soft cloth to clean. Do not use harsh detergents, solvents or splashing water etc. There is risk of fire, electric shock, or damage to the plastic parts of the product.
•Do not touch the metal parts of the product when removing the air filter. There is risk of personal injury.
•Do not step on or put anyting on the product. (outdoor units) There is risk of personal injury and failure of product.
•Always insert the filter securely after cleaning. Clean the filter every two weeks or more often if necessary. A dirty filter reduces the efficiency.
•Do not insert hands or other objects through the air inlet or outlet while the product is operating. There are sharp and moving parts that could cause personal injury.
•Be cautious when unpacking and installing the product. Sharp edges could cause injury.
•If the refrigerant gas leaks during the repair, do not touch the leakaing refrigerant gas. The refrigernat gas can cause frostbite (cold burn).
•Do not tilt the unit when removing or uninstalling it. The condensed water inside can spill.
•Do not mix air or gas other than the specified refrigerant used in the system. If air enters the refrigerant system, an excessively high pressure results, causing equipment damage or injury.
•If the refrigerant gas leaks during the installation, ventilate the area immediately. Otherwise it can be harmfull for your health.
•Dismantling the unit, treatment of the refrigerant oil and eventual parts should be done in accordance with local and national standards.

3Do not place animals and plants in the path of the warm air.
4Take the air conditioner weight into account and select a place where noise and vibration are minimum.
5Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.
6Place that can sufficiently endure the weight and vibration of the outdoor unit and where even installation is possible.
7Place that has no direct influence of snow or rain.
8Place with no danger of snowfall or icicle drop.
9Place without weak floor or base such as decrepit part of the building or with a lot of snow accumulation.
10 Sufficient ventilation is secured.
Rooftop Installations
If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure and anchoring method are adequate for the unit location. Consult local codes regarding rooftop mounting.
